2. DANIEL SZEGO Hyperledger Fabric: an in-depth introduction Azure Blockchain Zürich University Collaboration Several universities want to set up an educational consortium to provide a better way for the students for university exchange and to acredite courses and degrees overall. The system is based on several cross university workflows and business processes. Use Case link: https://github.com/Azure-Samples/blockchain/tree/master/blockchain-workbench/application-and-smart-contract-samples/simple-marketplace Consortium scenario NO: - no cryptocurrency - no public tokens - no public ledger BUT: - identity management - permissions - system integration
3. DANIEL SZEGO Hyperledger Fabric: an in-depth introduction Azure Blockchain Zürich Requirements 1 Semi trusted blockchain setup: the consortium members do not fully trust each other, but they know each other, implying a crypto-economically less secure but faster consensus mechanisms. 2 Privacy preserving is usually on a need to know basis. Identity, including the integration possibility of third party identity providers is important. 3 There is no cryptocurrency and no public crypto asset in the system. Hence regulation should be able to realize in a more compliant way, like KYC, AML, GDPR. 4 Enterprise system integration and compliance with the existing systems, like infrastructure, existing databases, ledgers, identity management ... Consortium and Enterprise Blockchain

6. DANIEL SZEGO Hyperledger Fabric: an in-depth introduction Azure Blockchain Zürich Architecture Hyperledger Fabric is a general consortium blockchain platform. The core architecture contains a splitted consensus mechanism, chains for privacy, membership service provider and certificate authorities for identities. 1. Comitter peer: commits transactions,maintains ledger and state. 2. Endorsing peer: receives a transaction proposal for endorsement, responds granting or denying endorsement. 3. Ordering peer: approves the inclusion of transaction blocks into the ledger and communicates with peer and endorsing peer nodes. Fabric Overview Link: https://www.hyperledger.org/projects/fabric
7. DANIEL SZEGO Hyperledger Fabric: an in-depth introduction Azure Blockchain Zürich Architecture Chaincode: smart contract in Hyperledger Fabric implemented in Go, NodeJS or Java (with some hacking solidity is also possible) MSP - Membership service provider: assigning identities to actors, nodes and transactions with the help of certificate authority ervices. Channel: independent blockchains from the ledger storage point of view - privacy and scalability Fabric Overview Link: https://www.hyperledger.org/projects/fabric
